  • Patent number: 7946754
    Abstract: A clockwork movement includes a control member actuatable by a control lever in response to a user's action and having the form of a column wheel. The control member is rotatably mounted on the clockwork movement frame around an axis X, perpendicular thereto, for controlling first and second mechanisms exhibiting at least one movement function such as chronograph or alarm function. The control member includes rotationally fixable first, second and third parts which are mounted on a shaft at first, second and third levels, respectively, in a direction of the axis X for interacting with the control lever and for controlling the mechanisms. The shaft which is pivotally mounted with respect to the frame is arranged in at least two bearings, which are positioned remotely to each other for ensuring the shaft good stability, whereas the second and third parts are located on the both parts of the frame.

  • Patent number: 7780341
    Abstract: A clockwork movement includes at least two control elements which are movable with respect to the frame thereof, are used for interacting with the same external control member in response to the activation thereof and are positioned remotely to each other in the direction of the clockwork movement thickness. The clockwork movement has an intermediate connecting unit which is rotatable about an axis substantially extending in the direction of the clockwork movement thickness, pivotally mounted on the clockwork movement frame element and provided with a reception area which is distant from the axis and exposable to a force produced in response to the control member activation. The intermediate unit also includes at least two contact areas each of which is used for producing a force on the corresponding control element and which are located on both sides of the reception area in the direction of the axis.

  • Patent number: 7597471
    Abstract: A chronograph clockwork movement for measuring time includes a control lever actuatable by a first control member for alternatively activating or deactivating a time measurement, clutch elements for driving or not a second timer in response to an action produced on the control lever and selective locking members for locking the second timer in response to an action produced on the control lever. A lever and a hammer for resetting the second timer to zero are also provided. The clockwork movement is arranged in such a way that a user does not feel any difference, while measuring a time, whether the second timer is pre-set or not. The clockwork movement has a structure enabling to activate time measuring by delaying the effective departure of the second timer until an external resetting device controlling the lever is released in the rest position thereof.

  • Patent number: 7553067
    Abstract: A clockwork movement hammer (1) is used for interacting with heart-shaped cams (20, 21) provided with corresponding axes of rotation (29, 30) which are positioned remotely to each other. More precisely, the hearts (20, 21) are connected to a chronograph timer, whereas the hammer belongs to the resetting mechanism of the chronograph timers. The inventive hammer (1) includes at least one first part (5) movably mounted on the clockwork bottom plate (2) and one second part (17) bearing supporting surfaces (13, 19) which can be bring into contact with the hearts (20, 21) . The two parts (5, 17) of the hammer (1) are connected to each other by at least one swivel-type connection (14, 24) for making it possible to adjust the corresponding positions of the supporting surfaces (18, 19) while a resetting process. Due to particular characteristics thereof, the structural design of the hammer (1) is simple and small-sized.

  • Publication number: 20070147179
    Abstract: A timepiece, in particular a wristwatch, includes a constant-force device for acting on an oscillating system, the constant-force device including a switching unit and a tensioning module having a primary spring-energy store and a secondary spring-energy store. A seconds shaft bearing a seconds wheel and a cam plate is driven to rotate constantly by the secondary spring-energy store. The seconds wheel drives the oscillating system, and the cam plate acts on the switching unit for the periodic tensioning of the secondary spring-energy store by the primary spring-energy store.

  • Publication number: 20070140067
    Abstract: A timepiece includes a casing having a casing interior having a viewer's side provided with a viewing opening, a base side provided with a sound aperture, and an annular surface surrounding the sound aperture. A membrane extending over the sound aperture closes the base side of the casing interior, the membrane having a circumferential region in sealed connection with the annular surface. A tensioning device maintains the membrane at a desired tension in the radial direction. A vibration generator arranged in the casing interior produces a sound whose frequency can be adjusted by adjusting the tension of the membrane.

  • Patent number: 6809992
    Abstract: A clock with a twenty four hour display includes a minute hand, a second hand, a minute scale, a date display, and an hour scale on a first conchoid. The first conchoid includes an outer loop for the hours of the day from 6-18 hours and an inner loop for the hours of the day from 18-6. A crossing point of the inner and outer loops is established at the hours of 6 and 18. To achieve unambiguous indication, the hour hand is made variable in length. In a second conchoid offset by a constant amount radially inwards with respect to the first conchoid, which for instance is milled in the form of a groove in the dial, a guiding element is moved azimuthally through the inner part of the hour hand, which receives an overlay of radial movement owing to the shape of the second conchoid. The second conchoid and the guiding element may be covered by a disc joined to the inner part of the hour hand and turning with it.
